A number of people have reported problems with matplotlib in
non-default install locations.  I'll try and get these cleared up
before the next release.

Thanks!

Your error message suggests to me that you have an out-of-day CVS
copy, which is not surprising since sourceforge seems to have problem
staying current.

Grab another copy when you get the chance and let me know if you have
any more problems.

Hello,

I just tried out the wxpython backend from the CVS and it seems to work 
as advertised, except a small glitch.

I had matplotlib installed in another location, not under the default 
python main tree and use the environmental variable AFMPATH to point to 
the afm fonts files. The backend_wx(.py) relies on 
distutils.sysconfig.PREFIX to find the GUI bitmap files. Adding the 
following 2 lines

     if os.environ.has_key('AFMPATH'):
         basedir = os.environ['AFMPATH']

after the line

basedir = os.path.join(distutils.sysconfig.PREFIX, 'share', 'matplotlib')

in the function  _load_bitmap(filename) will enable it to locate the 
bitmap files which are installed together with the afm font files. (As 
AFMPATH points to more than font resources, a more appropriate name such 
as MATPLOTLIBRESOURCE may be warranted, though changing it will break 
old installations. I'm happy to let it stay as it is.)

Regards,
ST
